3 PUT YOUR TRUST IN A PERFECT COMBINATION OF EXPERIENCE AND INNOVATION WACKER is one of the world s leading suppliers of high-quality binders and polymer additives. WACKER scientists have been working with polymeric binders since the 1950s, and with highperformance vinyl acetate/ethylene (VAE) copolymer dispersions since the mid-1960s. Now, WACKER is the market and technology leader in VAE dispersions with world class production sites in the Americas, Europe and Asia. The future belongs to environmentally friendly systems. WACKER supplies you with an important component of such systems: a product range that includes low-voc, FDA-compliant and non-apeo surfactant stabilized binders, but still offers full performance and in many cases cost advantages. Your Innovative Boost We complement our production and market experience with our tradition as a hands-on innovation partner to our customers throughout the world. That makes WACKER one of the most research-intensive chemical companies in the world, maintaining its own research department to secure an innovative lead for WACKER and its customers. Your Market Lead Complementing our research, our technical centers provide support for customers worldwide. The technical centers are locally based, globally networked, cuttingedge laboratories, which will assist you in your specific applications, modify products to your specifications, test different systems or analyze new formulations. Your Competitive Advantage The in-depth product know-how that we have gained, together with our long experience in manufacturing and marketing, has resulted in a portfolio that is as mature as it is innovative. Most recent developments are oriented to tomorrow s demands. They meet requirements for sustainability and environmental compatibility while offering optimum cost/benefit. And, of course, they perform the most important function: optimizing the properties of your products to give them a competitive edge. Your Partners High solids adhesives, solvent- and plasticizer-free binders, low-formaldehyde products there are many applications where the future sets us new challenges. We want to overcome these challenges together with you. Just contact us! WACKER, VINNAPAS and VINNOL are registered trademarks of Wacker Chemie AG. 3

4 FOR ADHESIVES THAT COMBINE EFFICIENCY AND PERFORMANCE High-performance products with low environmental impact. Many of our VINNAPAS and VINNOL dispersions for the adhesives market are characterized as water-based, solvent-free, plasticizer-free, low-formaldehyde and low-voc products that offer excellent opportunities for growth. With their superior performance and cost advantages, these dispersions offer alternatives to many other technologies. WACKER s product line includes vinyl acetate/ethylene (VAE) copolymer dispersions and polyvinyl acetate (PVAc) water resistant homopolymer dispersions. VAEs function as high-quality binders, providing adhesion and cohesion, hydrolytic stability, thermal stability, high degrees of wet tack, fast setting speeds, high solids content and excellent resistance to plasticizers. VAEs boast an exceptional range of properties, allowing them to bond a wide range of different substrates, to have a broad formulation latitude and be applied via a host of high-speed application methods. In over 70 years of development and production of polymer dispersions, we have gathered extensive experience and expertise, which is reflected in our unique product portfolio. VINNAPAS and VINNOL dispersions are particularly suitable for formulating very low-emission dispersion adhesives, and are therefore highly valued for bonding coated paperboard, PVC, rubber, linoleum, polyolefin, cork and textile coverings used in a wide range of applications including: Automotive Bookbinding Case and carton packaging Cigarette manufacturing Cups and tube winding Envelope manufacturing EPI adhesives Flooring Foil and film laminating Furniture laminating Glass and cellulose insulation Glass and plastic bottle labeling Membrane pressing Multiwall and specialty bags PVC laminating Underlayments Vacuum forming Wood adhesives 4

5 VINNAPAS and VINNOL dispersions are impressive for their excellent quality and can be protected with colloid systems, surfactant systems, or a combination of both. The most common colloid system used in adhesive applications is polyvinyl alcohol (PVOH). PVOH is a large molecule that is water soluble. It will therefore contribute a high degree of wet tack to a dispersion that is not possible with surfactant protection. VAE dispersions protected with partially hydrolyzed PVOH can be readily machine applied and are non-spattering. They display fast setting, have good flow and are easy to clean up. Surfactant-protected systems are much more thixotropic than PVOH-stabilized dispersions and become thinner under high shear conditions. Advantages of surfactant-protected dispersions include lower heat-seal temperature, better adhesion to plastics, clearer films, higher water resistance and good sprayability. In some cases, our dispersions are polymerized with a combination of protective colloids and surfactants to achieve the best combination of performance attributes. VINNAPAS and VINNOL dispersions offer a wide range of products so that compounders can formulate or blend an adhesive product that will exhibit the best performance balance for their end customer s adhesive application. 5
